Utilize AngularJS to implement ngClick function through JavaScript

As I work on a small web page for mobile devices using Angular, I am looking to implement a toggle click listener for the entire page. However, I want to achieve this in an Angular-specific way without resorting to using ng-Click with conditional statements since most of the time the click functionality should not be active and is primarily for error handling purposes. Can this be done within Angular or do I need to rely on pure JavaScript/jQuery?

Here is the HTML code for the panel:

<div class="alert error" ng-show="errorMessage">
    <div class="alert-text">{{ errorMessage }}</div>
</div>

javascript angularjs addeventlistener angularjs-ng-click

Answer №1

I have developed a custom directive:

It is meant to be used in conjunction with ngIf.
The ngIf should point to an assignable variable within the scope.
For instance, avoid using: ng-if='myFunc()' or ng-if='var1 || var2'

You can find a working example on Plunker here: http://plnkr.co/edit/fmNH2PbRrruRqGFYiui1?p=preview

Custom Directive:

app.directive('errorBox', function($document, $parse){
  return {
    link: function(scope, elm, attrs) {
      var clickHandler = function(){
        scope.$apply(function(){
           $parse(attrs.ngIf).assign(scope.$parent,'')
        })
        $document.off('click', clickHandler);
      };

      $document.on('click', clickHandler)
    }
  }
});

HTML Code:

<div ng-if="errorMessage" error-box class="alert error">
  <div class="alert-text">{{ errorMessage }}</div>
</div>

To ensure that clicking is allowed, you can create a $scope variable for tracking. Here is an example of how you can implement this:

<div ng-click="isEnabled || performAction()"></div>
